活体成像技术已经显著地推进了神经损伤和轴突变性的领域;然而,研究仍然主要在体外环境中进行,例如培养的神经元细胞或在较低的模型生物体中进行,例如C.轴突没有胶质包裹的秀丽线虫。我们最近开发了一种新的成年期神经损伤的体内模型,在强大的模式生物黑腹果蝇,使用动物的高度可访问的翅膀。由于果蝇翅膀是半透明的,并且为了生存而存活,它允许清晰和直接地可视化损伤诱导的轴突和神经胶质的渐进反应,这些反应随着时间的推移在活体动物上由荧光蛋白标记物突出显示。此外,与以前的果蝇神经损伤模型不同,该过程不需要解剖中枢神经系统(CNS)。因此,本方案中描述的神经损伤反应的体内成像的关键准备步骤可以在30分钟内完成。
Live imaging technology has significantly advanced the field of neural injury and axon degeneration; however, studies are still predominantly performed in in vitro settings such as cultured neuronal cells or in lower model organisms such as C. elegans where axons lack glial wrappings. We recently developed a new in vivo model for adult-stage neural injury in the powerful model organism Drosophila melanogaster, using the highly accessible wing of the animal. Because the Drosophila wing is translucent and dispensable for survival, it allows clear and direct visualization of injury-induced progressive responses of axons and glia highlighted by fluorescent protein markers on live animals over time. Moreover, unlike previous Drosophila models of neural injury, this procedure does not require dissection of the central nervous system (CNS). Thus, the key preparation steps for in vivo imaging of neural injury response described in this protocol can be completed within 30 min.
